Gasoline is primarily composed of iso-octane, which has the chemical formula C8H18. When gasoline is burned, the chemical equation is: 2C8H18  +  25O2  --->  16CO2 + 18H2O This means that 2 molecules of iso-octane combine with 25 oxygen molecules to produce 16 carbon dioxide molecules and 18 water molecules. Use of fossil fuels adds CO2, carbon dioxide, to the atmosphere. This human-generated CO2 increases the planetary greenhouse effect, leading to an increase in average land surface temperatures, accumulation of heat in the oceans, and modification of global climate. Part of the problem is that a lot of CO2 is produced per mass of fuel burned. You can see that by looking at the fraction of carbon in iso-octane and carbon dioxide. 1. Calculate the formula masses of iso-octane (C8H18) and carbon dioxide (CO2) 2. What is the percent composition of carbon (C) in C8H18 and CO2?

In one reaction, 41.2 g of Cu(NO3)2 is produced. What amount (in mol) of CuCl2 was consumed? What mass (in grams) of AgCl is produced? mol CuCl2 consumed g AgCl produced

Ethane is a gas similar to methane that burns in oxygen to give carbon dioxide gas and steam. The steam condenses to form water droplets. The chemical equation for this reaction is C2H6 + O2 → CO2 + H2O. Balance this equation.

Acrylonitrile is an important building block for synthetic fibers and plastics. Over 2 billion pounds of acrylonitrile are produced in the United States each year. The compound is synthesized from propene in the following reaction:2C3H6 + 2NH3 + 3O2 → 2C3H3N + 6H2OWhat mass of acrylonitrile can be prepared from 150.0 kg of propene, 600.0 kg of ammonia, and 100.0 kg of oxygen?
